Esmolol
Esmolol is an ultra-short-acting, cardioselective, beta-1 adrenergic receptor antagonist. Its ultra-short duration of action makes it uniquely suited for the dynamic environment of the operating room.

EMLA Cream
EMLA stands for Eutectic Mixture of Local Anesthetics. It is a topical anesthetic used to provide temporary, superficial analgesia of intact skin. Its utility lies in its ability to reduce the pain of needle procedures, making it an invaluable tool, especially in pediatrics and for patients with needle phobia.
Entonox
Entonox is a pre-mixed, colorless, non-flammable gas consisting of 50% nitrous oxide (N₂O) and 50% oxygen (O₂). It is a fundamental and widely used analgesic in many clinical settings, from the emergency department to the delivery suite.
Etomidate
Etomidate is a potent, non-barbiturate hypnotic agent used for the induction of general anesthesia. Its primary claim to fame is its remarkable hemodynamic stability, making it a go-to drug for patients with compromised cardiovascular function.
Dantrolene Sodium
Dantrolene is the definitive, life-saving antidote for Malignant Hyperthermia (MH), a rare but fulminant hypermetabolic crisis triggered by specific anesthetic agents. It is a direct-acting skeletal muscle relaxant that works at the cellular level, not at the neuromuscular junction.
Dexamethasone
Dexamethasone is a long-acting glucocorticoid essential for anesthesiologists. It’s a cornerstone of ERAS protocols, providing potent prophylaxis against PONV, reducing airway and tissue edema, and offering opioid-sparing analgesia. While highly effective, its use requires careful monitoring for perioperative hyperglycemia, especially in diabetic patients.
Dobutamine
Dobutamine is a potent synthetic inotrope primarily acting on β1-adrenergic receptors to dramatically increase cardiac contractility. Its principal role is in managing acute decompensated heart failure and other low cardiac output states, where the therapeutic goal is to boost the heart’s pumping force without significantly increasing vascular resistance.
Dopamine
Dopamine is a potent endogenous neurotransmitter used clinically as a vasopressor and inotrope, uniquely characterized by its dose-dependent effects on the cardiovascular system. At low doses, it acts on dopaminergic receptors to increase renal blood flow; at intermediate doses, it stimulates β1-receptors to boost cardiac contractility; and at high doses, it activates α1-receptors to cause potent vasoconstriction.
Diclofenac Sodium
For the anesthesiologist, diclofenac is a valuable tool for opioid-sparing, multimodal analgesia. Its use demands a strict risk-benefit analysis, vigilantly balancing its potent anti-inflammatory pain relief against the significant perioperative dangers of bleeding, renal injury, and gastrointestinal complications.
Cisatracurium
Cisatracurium offers predictable paralysis with unique advantages. Its organ-independent metabolism and lack of histamine release make it perfect for hemodynamically unstable patients and those with renal or hepatic failure. Discover why this NMBA is a critical tool in modern anesthesia and critical care.
